down to 0.05mm (0.002") at line speeds up
to 3,000m/min (9,842ft/min).
The LN3040 is designed with a user-friendly
operator interface, accepts a range of
inputs, and can be easily connected to
a host PC or PLC using RS-232, Ethernet/
IP, DeviceNet, Profibus, and Profinet. Beta
LaserMike also offers the three-axis LN3015
lump and neckdown detector with the
same robust features, flaw detection
capabilities, and communications as the
LN3040, but with a smaller footprint. The
LN3015 measures product diameters up to
15mm (0.59").
In addition to the new product releases,
Beta LaserMike will present its solutions for
automated cable testing. On display is the
DCM Model SCS-350B for quality testing
4-pair Category LAN/data cables up to
600MHz. This compact, bench-top system
efficiently tests Cat 5/5e/6/6A unshielded
(UTP) and shielded (STP/FTP) twisted-pair
cables with a high degree of precision.
The company offers a full line of DCM
cable testing solutions for testing LAN/data,
Telecom, RF/coaxial, and aerospace/
defense cables. Products include fast,
reliable solid-state switching technology
to automate cable-testing functions and
can be integrated with powerful vector
network analyzers (VNAs) for a complete
high-performance testing system. The DCM
line of cable testing systems is engineered
to deliver the highest quality results,
performance, and value for the investment.
The company will also be delivering a
technical presentation to cable producers
on the latest in coupling attenuation testing
and how it complies with current industry
specification requirements for Category 8
cable.
The paper, entitled ‘Coupling Attenuation
(CA) Testing for Category 8 Compliance’,
will be co-presented by Rafael Herrera,
chief engineer for DCM Cable Testing
Systems andNadimKafati, systems engineer
at Beta LaserMike, in session four during the
morning.
The paper highlights the use of tri-axial
chamber technology to determine the
minimum and maximum limits for CA
measurements, and also presents data
from testing F/UTP and S/FTP cables from
30 MHz to 2 GHz. The data acquired will be
compared with the proposed Category 8
specification limits, and will show how the
tested cables compare to the proposed
specification requirements.
In addition, the paper looks at differential-
to-common mode conversion and its effect
as a noise source in LAN cables. The noise
performance of a LAN cable is directly
related to the pair balance. Transverse
Conversion Loss (TCL) is a parameter
that is used to specify the pair balance
requirements of LAN cables.
Thepaper provides TCLmeasurement results
of the tested cables. Finally, the paper
presents a technique that was devised to
evaluate the noise floor of the CA tri-axial
